To aJ/L whom it may concern.-

Be it known that I, J AMES SoMnRvILLn, a citizen of the United States,residing in the city of New York, in the county and State of New York,have invented a new and useful Improvement in Dump-Wagons, of which thefollowing is a specification.

My invention relates to an improvement in dump wagons, and moreparticularly improvements on the wagon patented to me on the 26th day ofNovember, 1901, numbered 687,277, the object being to overcome certainobjections made against that shown and described in said Letters Patentand to provide dumping mechanism so constructed and arranged as to workquickly, with perfect safety to the operator, and with but little labor.

A further object of my invention is to provide a bottom, frame, or bedhaving its two sides so extended as to permit of the use of substantialsprings on the rear part of the wagon, forming a solid support for therear part of the body and overcoming the objection made against theformer structures employing much smaller springs.

With these and other ends in view the in vention consists in certainnovel features of construction and combinations of parts, as will behereinafter fully described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a plan View of my improvedwagon, the body being removed for the sake of clearness. Fig. 2 is asectional view thereof, showing the body in an inclined position readyto be dumped. Fig. 3 is a View in side elevation, the body being shownin the carrying position. Fig. 4 is a rear end view of the body. Fig. 5is a view in perspective of a locking bar or device for employment onthe forward part of the wagon. Fig. 6 is a view of the spud foremployment with the locking device. Fig. 7 is a detached view of thelocking device for the tail-board. Fig. 8 is a sectional view taken onthe line 8 8 of Fig. 1. Fig. 9 is a view in perspective of the dumphook. Fig. 10 is a perspective view of the clumpstop. Fig. 11 is a sideview of the guideblock, and Fig. 12 is a top plan View of the same. Fig.13 is a view of one of the slides. Fig. 11 is a detached side view ofthe handle for operating the dumping-body, and Fig. 15 is a face viewthereof. Fig. 16 is a sectional view taken on the line 16 16 of Fig.14:.

Referring to the drawings, it will be seen extended a considerabledistance back of the rear axle 18, and cross-piece 19, front piece 20,cross-bar 21, inner side pieces 22, and the center pieces 23 24,mortised or otherwise secured together. Between the center pieces 23 24and at the rear end of the same is secured the double roller 25, andbetween the same at their forward ends is secured the double sprocket26, having formed on one end thereof the gear 27. Around the doubleroller 25 and the double sprocket 26 pass the endless chains 27 the endsbeing connected to the guide-block, 28, the latter, as illustrated inFigs. 8, 11, 12, and 13, consisting of the block proper, 28, the reducedends 29 of which fit in openings 30, formed in the guideplates 31, saidguide-plates being adapted to travel longitudinally between the metalplates 32, secured to the inner sides of the center pieces 23 2 1. Thereduced ends 29 of the block 28 also pass through the lower ends of thelifting bars or rods 33, which at their upper ends are pivoted to thebase of the wagonbody 31 toward the forward end thereof. This wagon-bodyis made of a suitable length and of such width as will allow it to betilted or inclined between the extended ends of the side pieces 17 ofthe frame, as illustrated in Fig. 2, the cross-piece 17, Fig. 1, of thewagon-body, however, resting on the side pieces 17 of the frame when thebody is in its carrying position. In order to retain the body in itsproper carrying position upon the frame, as illustrated in Fig. 3, Ipivotally sccure to the cross-piece 21 of the frame a locking-bar, asillustrated in Fig. 5, consisting of a bar 35, having its ends bentupwardly to form handles 36 and having formed on or secured thereto theplates 37, provided with openings 38, through which openings extend pinsor spuds 39, extending upwardly from the cross-piece of the body. henthe wagon-body is in its carrying position upon the frame of the wagon,the handles 36 are turned upwardly, in which position the plates 37 willlie flat, with the spuds 39 projecting through the openings 38,preventing the body 3 1 from sliding or moving backwardly upon theframe. When, however, it is desired to dump the wagon, the handles 36are turned downwardly, as illustrated in Fig. 2, thereby raising theplates 37 out of engagement with the pins or spuds 39 and leaving thebody free to be moved rearwardly upon the frame.

To the sides of the wagon-body are secured that the frame consists ofthe side pieces 17, 1 stops consisting, as illustrated in Fig. 10, of

IIO

the plates 41, having formed thereon or sei cured thereto the0utwardly-extending pins or lugs 43, which when the body is movedrearwardly to a certain extent engage with the hooks 44, formed on orsecured to the plates 1 45, bolted or otherwise fastened to the sidepieces 17 of the frame.

With the gear 27 meshes the gear 46, se i cured to the shaft 47, mountedon the side pieces 22 of the wagon-frame, the ends of i which bar or rod47 are squared in order to receive a crank or handle, as hereinafterdescribed. VVhen the gear 46, meshing with the gear 27 is rotated, thewagon-body 34, by means of the endless chains 27 and rods 33, will bemoved backwardly and rearwardly upon the frame until the stops 43 engagewith the hooks 44, whereupon by continuing to rotate the gear 46 therods 33 will cause the forward portion of the wagon-body to lift orraise, as shown in full lines, Fig. 2, until such time as the bodybecomes over-balanced, whereupon it will assume the dumping position, asillustrated in dotted lines, Fig. 2, the body resting upon thecross-piece 19 of the frame, said body inclining, as described, betweenthe extended ends of the side pieces 17 of the frame. By turning thegear 46 in the opposite direction the rods 33 will gradually return thebody to its inclined position, as illustrated in Fig. 2, and finallyinto its carrying position, as illustrated in Fig. 3, whereupon thehandles 36 of the locking-bar 35 may be raised, causing the plates 3'7to engage with the pins or spuds 39 and hold the parts in their normalpositions.

To the rear end of the wagon-body is hinged or pivotally secured theupper part of the tail-board 48, the lower free end of which is held inposition by means of the stop 49, which, as illustrated in Fig. 10,consists of the metal plate 49, pivoted near its lower end to the plate50, the latter being bolted or otherwise secured to the wagon-body 34.WVhen the body is in its carrying position, as illustrated in Fig. 3,the lower end of the pivoted stop or plate 49 will strike the ex: tendedend of the side piece 17 of the'frame, causing the upper end of saidplate or stop 49 to rest against the lower free end of the tail-board48, keeping the latter in its closed position. 1V hen, however, the body34 is moved rearwardly, the upper heavier end of the stop 49 will dropout of engagement with the lower end of said tail-board, allowing thelatter to open, as illustrated in Fig. 2, this construction andarrangement of parts causing the tail-board to be opened and closedautomatically and overcoming the necessity of releasing the same, as hasheretofore been required.

In Figs. 14, 15, and 16 I have illustrated the crank or handle 51, whichI have employed with good results in rotating the bar 47 with itsattached gear 46, to lift and dump 1 the wagon-body, said crank orhandle being provided with the spring-actuated ratchet 52 on the endthereof, said ratchet being adapted to operate in either direction bymeans of the dogs or pawls 53, maintained in their proper relativepositions by means of the springs 54,

, said ratchet being provided with the central squared opening 55 tocontain the squared ends of said bar or rod 47. hen it is desired todump the wagon, it is simply necessary to place said ratchet-handle 51upon either end of said rod 47 and by turning the same cause the body toraise and dump, as heretofore described, the ratchet allowing the gearsto turn and the body to dump while the handle remains stationary. Whenit is desired to return the wagon-body to its normal position, theopposite dog or pawl 53 is thrown into engagement with the ratchet 52and the handle again turned as before, whereby the body is brought backto its normal position without the trouble of disengaging the crank fromthe shaft. Further, by the use of such a handle or. crank the operatoris protected from being struck, as is often the case when the ordinarycrank or handle is employed.

It will be understood from the foregoing that the wagon is of simple butsubstantial construction, may be easily, readily, and safely operated,and that by extending the side pieces of the frame with sufficientdistance between them to allow of the body to incline between them whenin the dumping position the rearward travel of said body iscomparatively short, said extensions at the same time affording a solidsupport for the rear end of the body by reason of the extension of therod 17, which rests upon said extended ends when said body is in thecarrying position.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. A wagon of the character described, constructed with a frame andmovable body, said frame being provided with extended side pieces andtwo central pieces, a roller carried by said center pieces at their rearends, and a sprocket-wheel at their forward ends, a guide-blocktraveling between said center pieces, an endless chain secured to saidguideblock and passing around said roller and sprocket-wheel, a rodpivoted to said guideblock and to the forward part of said body, meansfor moving chains and guide-block, whereby the body is moved into andout of the dumping position, and means for locking the body in itscarrying position, said lastnamed means including pins fixed to thewagon-body and a transverse locking-rod mounted on the frame andprovided with plates to engage with said pins, substantially asdescribed.

2. A wagon of the character described, constructed with a movable bodyand a frame, the latter being provided with extended side pieces betweenthe ends of which said body fits when in the dumping position, and alsowith two center pieces, a roller carried between said center pieces attheir rear ends, a sprocket-wheel located between said center pieces attheir forward ends, an endless chain passing around said roller andsprocketwheel, a guide-block secured to said chain and between saidcenter pieces, a rod pivoted to said guide-block and to the forward endof said body, means for movingsaid chain, whereby the body is moved intoand out of the dumping position, and means for locking the body in itscarrying position, said last-named means including pins fixed to thewagon-body and a transverse locking-rod mounted on the frame andprovided with plates to engage with said pins, substantially asdescribed.

3. A wagon of the character described, constructed with a movable bodyand a frame, the latter consisting of extended side pieces between theends of which said body fits when in the dumping position, center piecesforming part of said frame, a roller carried between said center piecesat their rear ends, a sprocket-wheel havingagear-wheel provided thereon,an endless chain passing around said roller and said sprocket-wheel, aguide-block secured to said chain and traveling between said centerpieces, a rod pivoted to said guidebloclz and to the forward part ofsaid body, a horizontally-extending rod mounted on said frame andprovided with a gear meshing with said former gears, said rod having anextended end adapted to receive a wrench for turning said rod wherebythe guide-block is caused to travel between said center pieces and movesaid body, substantially as described.

4. A wagon of the character described, constructed with a movable bodyand a frame, said frame being provided with extended side pieces betweenthe ends of which said body l fits when in the dumping position, meansfor moving said body on said frame, stops secured to said body, hookssecured to said extended side pieces, and with which engage said stopswhen said body is moved rearwardly, and means for locking the body inits carrying position said last-named means including pins on thewagon-body and a vertically-oscillating member having means for hookinginto engagement with said pins, substantially as described.

5. A wagon of the character described, constructed with a frame and amovable body, of pins secured to said wagon-body, and a transverselocking-rod mounted on said wagonframe and provided with perforatedplates adapted to engage with said pins on said wagon-body when thelatter is in the carrying position, substantially as described.

6. A wagon of the character described, constructed with a frame and amovable body, said frame having extended side pieces and said body beingprovided with a pivoted tailboard, and an automatic lock for saidtailboard, said lock consisting of a vertically-disposed plate pivotedto said body near its lower end and adapted to engage with the extendedside pieces of said wagon-frame, whereby said pivoted plate is raised toits vertical position said plate having the upper end heavier than thelower portion whereby itis overbalanced to release the tail-gate whenthe body is moved to carry the plate out of engagement with said sidepieces when the body is in its carrying position, substantially asdescribed.

In testimony that I claim the foregoing specification I have hereuntoset my hand this 30th day of November, 1904.
